if it fails, under warranty, they have to do the regular full fuel system replacement. i would *hope* that now there’s a Recall out for this issue they would have to do the full replacement even in the unlikely event you were already outside the Powertrain warranty.


but lets say you take yours in for the Recall ‘inspection’ and it’s determined that you do not have “contamination” (metal shards in the fuel), and they order the ‘simple’ kit.
when the parts finally come in and you go back for their installation months later, do they do the ‘inspection’ again to determine if failure has begun since it was last in?

seems to me like it should be a simple question (especially since the ‘inspection’ is so simple), but i have not gotten a dealer to answer this question yet.
I agree 100%. Metal shards in the fuel is the worse case scenario and cost more and much more labor to repair, but there seems to be a very small rate of failure of the pumps since the recall was announced over 6 months... ago.

Have we ever figured out if the recall “new” pump is actually anything different which will prevent the original issue of the pump lifters from shifting during cavitation and imploding the system? I’ve yet to bring it in for the service, but want to make sure it’s going to be worth the hassle and actually get a new part, not just a new part number

Great question. I've not been about find out if we'll be getting a revised version of the Bosch CP4 or if we're simply gettin a new potential ticking time bomb with a new (not improved) CP4. I would guess it's a redesign to address to widely known failure rate of this Bosch unit in our EcoDiesels and other diesel motors found in Fords and GMs.


If anyone is interested in knowing more about how the CP4 is failing, here's a decent video.

This is what gives me pause. I really don’t want to waste my time and effort in bringing my Jeep to get his recall done only to have the same problematic part reinstalled. If they could prove to me that the part installed is actually a new, problem resolved part, and it’s not a pump that takes a step backward in terms of pressure/operation/efficiency, then I’d feel better about it. The fact that Jeep can’t give us a straight answer on this worries me.

The youtube video in post #49 is very concerning. When the CP4 pump fails and contaminates the entire fuel system, not sure how much cost savings there is to Stellantis for the CP4 pump over the more robust CP3 pump.

I will have the recall performed as soon as my dealer tells me the parts are available. I fear that if I refuse the recall when parts become available, and then my pump fails, I don't want to be responsible for the failure.

Also, as stated above, it makes no sense to replace the HPFP with a new pump that may be subject to the same failure mode.

it wasn't just about cost; the CP4.2 makes more pressure than the CP3, which is part of why we get the power and fuel economy we do.
CP3 retrofits are available for some of the other applications that use(d) the CP4.2, but they don't end up getting the same power/economy.

i keep hoping we'll find out that the CP4.2 being provided under the Recall is something updated like the CPX was, but having worked with Bosch, i'm not holding my breath expecting them to be cooperative about them providing detail.

just for giggles, has anyone pinged @JeepCares about this question and gotten a response?

I just had mine replaced last Thursday. My situation was quite odd. I dropped the JL off in mid-November after scheduling an appointment in October. They called me a couple hours later, advising that the inspection was complete and they had ordered the necessary parts. They said they'd be in contact to schedule the repair once the parts were received. That call came in mid-December. I scheduled the drop-off for last Thursday and was advised when I dropped it off that a full fuel system replacement was required. They arranged a rental for me and indicated that they would need the JL for at least a week. A couple hours later, I got a call from the service department advising that the repair was complete and the JL was ready for pickup. I questioned them about what specifically was done (full fuel system replacement versus basic HPFP replacement), but I never got a clear response other than "We tell everyone to plan for a week, regardless of which type of repair is necessary."


Needless to say, there are still many unanswered questions. I popped the hood and couldn't even tell if anything was done, with the exception of a heavy diesel fuel odor that wasn't there before. I haven't looked deeper into it, so it's possible that they did change some parts, but there was no supplemental information included regarding the fuel requirements, nor was a recall modification sticker placed anywhere on the vehicle.

I hate to say it, but that sounds like a pretty typical Larry H Miller experience. The two dealers locally up here in CO are notorious for giving the same kind of garbage info to customers in the service department.
I called to get mine scheduled up with my dealer (Autonation) and they said they’d need to get parts on order (apparently back order is a thing already with these). Difference here is I trust them to get it done and give me the full story. They’ve never shy’d away from being transparent about what’s going on with my last 2 4xe’s and have always done right by me.
As soon as I go in and get it knocked out, I’ll be sure to post up any info they give me. Unfortunately with the backlog of 4xe work they have lined up already (it’s Denver so they’re everywhere out here) it sounds like the soonest I can expect it to happen is sometime in early February.

After being told I’d have to wait a year in Colorado to get my Z96 recall done, I took matters into my own hands.

Here are the part numbers needed to complete the work according to 2 dealers.

First 3 I found in store.mopar.com

68631088AA Pump $631
68211320AA Tube gasket $2.42
68211212AA Intake manifold gasket $9.62


68524869AA Tube kit - Moparpartsoverstock.com $215

FCA confirmed they will reimburse me for parts and labor is free at any Jeep dealer.
Good luck!

When I called to schedule service they were only a week out so they could order the part.

When I took it in I had it back in 24 hours. Same thing when looking under the hood, couldn’t even tell they were there.

I’d enjoy knowing what is different with the new pump as well.

Hello,
I’m finally getting the hpfp replaced next week. The question I have is whether or not my full skids are going to raise any problems with the dealer doing this work. Do they need to come off in order to replace the pump and lines ?
Last time I brought the jeep to investigate a clicking noise in the front end, they would even look at the jeep because it’s lifted.
Thanks.

Probably because they figured your ball joints were shot after seeing the lift and tires. Real savvy diagnostics on their part. ?

As for your other question, I'd pull anything blocking a clear path to the fuel filter and the tanks just to be safe. One less thing for them to try and use as an excuse to deny work.

That's a very poor service department. Extremely biased without cause. Future warranty service needs could be meant with huge constraints, contesting anything and everything they found caused by your modifications. Most common reason people purchase Jeep Wranglers, to customize. Some on the this Forum have mentioned an OEM K&N air filter drop in was the cause for codes, per the dealership.
Run ?‍♂ Forest run

The service manager runs the show. Go directly to him first when shopping for a new service department. Service departments that are unbiased on Wrangler mods. My service manager (located 1 hr. from home, passing several others) has owned several Wranglers in his lifetime. The lot generally has a few modified lifts and tires including 37s on the NEW fleet Wranglers and Gladiators not all "mopar" mods, in the lot. Start there. Good luck.

interesting, I heard that from another dealer "we have to inspect it to determine which parts to order". My understanding is that if the fuel pump implodes the vehicle will become un-driveable and have to be towed, otherwise the 4 parts are used for the repair...
That is correct if the pump implodes the vehicle will drive like crap, if its drivable at all....
